一、板式换热器的结构简介 板式换热器具有传热效率高,阻力少,适应性大,结构紧凑,维修方便,运行可靠等优点,是一种先进高效能的换热设备。 现以BR型为例简介其结构。该系列换热器主要由传热板片、密封垫(参见图1)、压紧板、进出口法兰接管、定位轴、框架以及压紧零件组成。由于换热器是组合而成的因此便于拆卸和清洗,同时也可以根据工艺的需要,增加或减少板片,甚至改变流程,具有很大的适应性。板片是使换热器具有许多优点的关键性零件,板片的波纹增加了有
First, the structure of the plate heat exchanger Brief introduction Plate heat exchanger with high heat transfer efficiency, low resistance, adaptability, compact structure, easy maintenance, reliable operation, is an advanced high-performance heat transfer equipment. Take BR as an example to introduce its structure. This series of heat exchangers is mainly composed of heat transfer plates, seals (see Figure 1), pressure plates, inlet and outlet flanges, positioning shafts, frames, and compression parts. Since the heat exchangers are combined, they are easy to disassemble and clean, and at the same time, they can increase or decrease the number of plates or even change the flow according to the needs of the process, and have great adaptability. Plates are the key parts that make the heat exchangers have many advantages. The ripples on the plates increase.
